Description

Technical Field

[0001] The utility model relates to the technical field of automobile rearview mirrors, in particular to an electronic rearview mirror. Background Art

[0002] Traditional automotive rearview mirrors use lenses with fixed viewing angles. While these lenses help drivers see around the vehicle to some extent, blind spots still exist, particularly near the A-pillars, posing a potential threat to driving safety. With the advancement of electronic technology, electronic rearview mirrors are gradually replacing traditional mirrors. These mirrors typically capture images through cameras and display them on in-car displays, providing a wider field of view. However, most electronic rearview mirrors currently on the market still use fixed or limited adjustment angles, failing to fully utilize the flexibility offered by electronic technology.

[0003] While some electronic rearview mirrors already offer some degree of adjustment, such as electrically adjustable mirror angle, these adjustments typically only work within a single plane and cannot achieve wide angles of rotation, thus still limiting the field of view. Furthermore, existing electronic rearview mirrors also present some inconveniences in terms of wiring and installation, such as wires that can easily interfere with lens rotation and a complex installation process. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present invention proposes an electronic rearview mirror with dual rotating lenses. Through the dual-lens design and the rotation function of the lens, the driving field of view is greatly expanded, blind spots such as the A-pillar are effectively avoided, and driving safety performance is improved. At the same time, the present invention also solves the problems of wire interference and inconvenient installation through the sophisticated wiring slot and annular shaft design.

The upper shell 5 and the lower shell 6 are both provided with snap springs 7, wherein two are provided on the upper shell 5 and one is provided on the lower shell 6. A fixing slot 103 is opened in the rearview mirror housing 1 corresponding to the snap spring 7. The rearview mirror housing 1 is mounted on the upper shell 5 and the lower shell 6;

[0041] The base 2 is fixedly connected to the sides of the upper shell 5 and the lower shell 6 by screws. A connecting bracket 8 is installed in the inner cavity of the base 2. The connecting bracket 8 is used to fix the electronic rearview mirror as a whole to the vehicle body;

[0042] A first lens assembly 3 and a second lens assembly 4, which are mounted in an upper housing 5 and a lower housing 6;

[0043] The first lens assembly 3 includes: a first motor 301, a first lens support frame 302, a first lens body 303, and a first annular shaft 304. The output shaft of the first motor 301 is fixedly connected to the first lens support frame 302. The first lens body 303 is mounted within the first lens support frame 302. The first annular shaft 304 is integrally formed on the first lens support frame 302. The first annular shaft 304 is disposed on the opposite side of the first motor 301. The first motor 301 can drive the first lens body 303 to rotate vertically.

[0044] The second lens assembly 4 includes: a second motor 401, a second lens support frame 402, a second lens body 403, and a second annular rotating shaft 404. A driving gear 405 is installed on the output shaft of the second motor 401. The driving gear 405 is engaged with the driven gear 406 for transmitting power. The driven gear 406 is fixedly installed at the bottom of the second lens support frame 402. The second lens body 403 is mounted in the second lens support frame 402. The top of the second lens support frame 402 is integrally formed with a second annular rotating shaft 404. The second motor 401 can drive the second lens body 403 to rotate horizontally. A limiting boss 601 is installed on the lower shell 6. The limiting boss 601 is arranged on the inner side of the second viewport 102 corresponding to the driven gear 406. The driven gear 406 is set to a fan-shaped structure. The limiting boss 601 is used to limit the rotation angle of the second lens body 403.

[0045] A wiring groove 501 is provided on the top surface of the upper shell 5 and the contact surface with the base 2. The wiring groove 501 is Y-shaped. The input end of the wiring groove 501 corresponds to the wiring port 202 provided on the base 2, and the output end of the wiring groove 501 corresponds to the first annular rotating shaft 304 and the second annular rotating shaft 404 respectively. The annular interior of the first annular rotating shaft 304 and the second annular rotating shaft 404 can lay lines to the first lens body 303 and the second lens body 403. The first annular rotating shaft 304 and the second annular rotating shaft 404 can ensure that the rotation of the first lens body 303 and the second lens body 403 is not affected by the wires.

[0046] The connecting bracket 8 is an integral injection-molded structure, which includes a rearview mirror connecting end 801 connected to the base 2 and a body connecting end 802 connected to the car. A through groove 803 is provided at the center of the body connecting end 802 of the connecting bracket 8. The through groove 803 corresponds to the wiring port 202, which can facilitate wiring.

[0048] The working principle of the present invention is as follows: when the driver needs to observe the situation around the vehicle, the first lens assembly 3 and the second lens assembly 4 will respectively capture images in different directions and transmit them to the display screen inside the vehicle. The first lens assembly 3 can be driven by the first motor 301 to achieve vertical rotation, so as to observe the situation behind and to the side of the vehicle. The second lens assembly 4 is driven by the second motor 401 and the gear transmission to achieve horizontal rotation, so as to observe the situation to the side and in front of the vehicle.

[0049] To ensure that the wire connection is not disturbed when the lens rotates, the utility model adopts a Y-shaped wiring groove and a ring shaft design. The wire is laid into the ring shaft through the Y-shaped wiring groove, and then rotates with the rotation of the lens. It is consistent with the rotation axis of the lens, and there is no pulling, so it will not interfere with the rotation of the lens.

[0050] A through slot 803 is provided at the center of the body connection end 802 on the connecting bracket 8 to facilitate the passage of wires. The downwardly curved hook 804 on the body connection end 802 is used to pre-fix it on the vehicle door during assembly, simplifying the installation process.

[0051] The electronic rearview mirror of this utility model significantly improves the breadth of driving vision, reduces blind spots, and enhances driving safety through its dual-lens design and free rotation function. At the same time, through the sophisticated wiring groove and annular shaft design, it solves the problems of wire interference and inconvenient installation, providing the driver with a more convenient and safe driving experience.
